I am not too trusted with a guaranteed profit because it looks suspicious and how if we lose? Do they guarantee to refund the loss?
Maybe @OP can change the "guaranteed profit" sentence to other things that will not look too good to be true or could be like "profit together" or others.
Full refund is usual in any service but not many of them can really give that if something worst happen because usually, many of them are run away if the things are not running as promised.
If @OP has had many winnings before, maybe he can share here or share his tip to us for a while to show that he has skills in UFC so it will not look like a shady service.
